GLAZING TOOLS Filed Oct. 10, 1951 Dmitri Vai/ 1N VENTOR ATTORNEYS United States Patent This invention relates to new and useful improvements in glazing tools.

One object of the invention is to provide an improved implement or tool for glazing panes in window sashes or doors which is of such construction that the glazing material or putty is cut cleanly and removed from the pane simultaneously with the smoothing of said material.

Another object of the invention is to provide an improved glazing tool having a pair of blades formed with edges disposed in angular relationship, the edge of one blade being arranged to apply and, smooth putty and the edge of the other blade engaging and removing or scraping excess putty from the pane.

A further object of the invention is to provide an improved glazing tool, of the character described, wherein the scraping blade is inthe form of an auxiliary blade mounted on the other or glazing blade whereby the tool is of simplified, economical construction.

A particular object of the invention is to provide an improved glazing tool, of the character described, wherein the glazing blade has an edge adjacent and disposed angularly relative to the edges of the scraping and glazing blades for hearing against the pane to cut the putty at the time of smoothing and removing excess putty.

An important object of the invention is to provide an improved glazing tool, of the character described, wherein a portion of the cutting-edge of the glazing blade protrudes laterally outward so as to permit spacing of the adjacent portions of the scraping and cutting edges from the pane and putty to. reduce the drag or pull of said edge portions against the-putty and the forming of burrs on said putty, and which facilitate use of the tool along the margins in the corner of thepane'. 1

Still another object of the invention is to provide an improved glazing tool, of the character described, wherein the auxiliary scraping blade extends from and in overlying relation to the glazing edge of the glazing blade and has a scraping edge at each end for coacting with said glazing edge whereby the tool is reversible and may be used on any side of a pane and in either direction.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the specification and by reference to the accompanying drawing, wherein examples of the invention are shown, and wherein:

Fig. 1 is a perspective view of a glazing tool constructed in accordance with the invention and showing its relation to the upper corner of a glass pane,

Fig. 2 is a view, similar to Fig. 1, showing its relation to the lower corner of a pane,

Fig. 3 is an underside plan view of the blade end of the tool,

Fig. 4 is a side elevational view of the blade end of the tool, and

In the drawing, the numeral 10 designates an implement or tool for glazing a glass pane or panel 11 in the frame 12 of a sash, door or other closure. It is preferable for the tool 10 to be in the'form of a knife and includes a thin, fiat, glazing blade or member 13 of relatively rigid metal, plastic or other suitable material. The blade 13 has a reduced shank 14 which may be mounted in a suitable handle 15. As shown in Figs. 3 and 4, a transverse, straight edge 16 is provided at the outer end of the blade for applying and smoothing putty or other glazing material 17 I An auxiliary scraping blade or member 18 is pro vided at the outer end of the glazing blade preferably by an integral coextensive flange projecting substantially at a right angle from the transverse, straight edge 16; however, the blade 18 could be removably attached to the glazing blade. The blade 18 is fiat and has one or a pair of outwardly inclined or diverging end edges 19 and 20 extending at obtuse angles from the ends of the edge 16 for engaging the pane 11 to scrape or remove excess putty therefrom. It is noted that the end edges 19 and 20 are straight and function aslrests or guides for the glazing blade so as to determine the angle of the exposed surface of the putty 17 to the pane. As shown in Fig. 1, the leftedge 19 is adapted to contact the pane when the-left-hand portion of the edge 16 is in engagement with the putty. Conversely, when the right-hand portion of the edge 16 is in engagement with the putty, the right edge 20 is adaapted to con tact the pane. Thus, the tool is reversible and may be used on any margin of the pane in either direction.

Immediately inward of its transverse or glazing edge, a portion of one or both of the longitudinal margins of the blade 13 projects laterally outward to provide one or a pair of laterally extending or protruding edges 21. These edges are preferably bowed or curved and are adapted to bear against the pane and cut the putty 17 along a line of demarcation 22 between said putty and pane. As shown in dotted lines in Fig. 1,, due to the protrusion of each cutting edge 21, the adjacent portioils of the scraping edge 19 of the auxiliary blade 18 and said edge are spaced slightly from the pane and the demarcation line 22 of the putty when the medial portion of'said edge 21 bears against said pane. This 3 slight spacing of the adjacent edge portions reduces, the

drag or pull of said edge portions against the putty so as to substantially eliminate the forming of burrs 'along said line. It is noted that the slight spacing of the inner portion of the scraping blade from the pane and putty is insufficient to interfere with the removal of said putty from said pane. In use, the cutting edge normally contacts the pane ahead of the scraping edge to cleanly cut the putty.

As shown in full lines in Fig. 1, the putty 17 at the corners of the pane is adapted to be cut and squared by the transverse straight edge 16 and the demarcation line 22 is cut and formed by the portion of the cutting edge 21 adjacent the scraping edge 19 hearing against said pane. Upon movement of the tool longitudinally of the putty, the tool is adapted to be swung inwardly toward the pane so that the medial portion of the edge 21 bears against said pane and the adjacent portions of said edge and the edge 19 are spaced from the pane as shown in dotted lines. The line 22 of the putty is cut smoother and is more free of burrs due to this spacing. 1

When the tool approaches the lower corner of the pane, said tool is swung outwardly so that the edge 21 clears the putty applied to the transverse margin of said pane and said edge cuts and squares said corner (Fig. 2).

A modified glazing blade 23 is shown in Fig. 5 and has a similar transverse straight edge 24 and a similar auxiliary scraping blade 25 provided with outwardly diverging end edges 26. Loi igitudinal straight edges 27 are formed on the blade 23 in place of the projecting edges 21. With this form of blade, the tool is adapted to be used in a single relative position and is not adapted to be swung inwardly and outwardly relative to the pane. In other words, this tool is held so that the entire length of the edge 26 is substantially in engagement with the pane and the outer end portion of the edge 27 bears against said pane.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction may be made, within the scope of the appended claims, without departing from the spirit of the invention.
